COILER FOR CARDlNG-MACHINES, 84c.

SPECIFICATION forming part of Letters Patent No. 518,675, dated April 24, 1894.

Application filed June 23,1893. Serial No. 478,672. on model) T at whom it may concern:

Be it known thatI, HENRY MoDERMoTT, a citizen of the United States, residing. at Norwich, in the county of New London and State of Connecticut, have invented a certain new and useful Improvement in'Coilers for Carding-Machines, 820., which improvement is fully set forth and described in the following speci trated in the drawings, in which- Figure l is a side elevation of a can and coiler complete, having attached thereto my newly invented alarm mechanism. Fig. 2 is an elevation of the coiler head with its case in central, vertical section and Fig. 3 is a plan View with the hinged cap g removed. Fig. 4 is an enlarged, plan, view similar to Fig. 3 but with the condensing rolls and their driving mechanism removed. Fig. 5 is aside elevation of a portion of the disk that carries the coiler-tube, showing in proper relation thereto the alarm mechanism which forms the essential feature of my invention. Figs. 6, 7 and 8 show, detached, certain of the elements of said alarm mechanism, all being hereinafter described in. detail.

The coiler mechanism, as well as the mech-' anism for supporting and revolving the can, are here shown substantially the same as now in common use and I therefore make no claim to these mechanisms.

The reference letter aindicates the driving shaft of the coiler and can-rotating mechanisms, which shaft may receive motion from any convenient part of a carding machine, or railway head, as the case may be. This shaft a bears a miter gear a which meshes with a corresponding gear 19 secured to a vertical lower end of shaft 1). Secured to the side of gear a is a smaller gear 0 that meshes with a gear 0 which in turn meshes with and drives a large gear (1 whose upper portion is formed as a table (1' upon which a can a may be placed. The arrangement of the described train of gearing is such that the can supporting table d revolves very slowly.

f denotes a casing which projects forward over the table cl and to the rear side of this casing is hinged a similar casing g to which is hinged a cap or cover g. The casing f is formed with a large circular opening whose annular walls extend inward to provide a ledge f upon which is loosely seated a disk 72. with circumferential gear teeth that mesh with a gear f secured to the shaft I). When shaft 6 is caused to revolve the disk It is also set in revolution.

To the upper side of disk hissecured a tube h, set diagonally at such an inclination that its lower, or delivery, end is overa point midway the center and circumference of the can while its upper end is over the center of the can and immediately under a pair of condensing rolls t'1l' journaled in bearings secured in the hinged casing g. The shafts of these condensing rolls bear meshing gears 10- -76. and one of said shafts has also a miter gear 7& that is driven by the gear 19 already referred to. When the described mechanisms are in operation the can 6 is revolved slowly in one direction while the coiler-disk h is revolved somewhat fasterin the opposite direction and as the sliver passes downward between the rolls i-z" it enters. the tube 71. and is guided outward and delivered into can e. The combined movements of the can and disk 72. cause the sliver to continually coil upon itself within arm of lever o is-bentlaterally, so that it may pass outward through an opening in the cas-- thedisk h.

service the sliveraccurnulatesin the can eun H Secured to the inner side of the casing gis a bracket-arm m whose free end is extended to a point over an annular flange or ribh on the upper side of disk h, and upon this extendedeend of bracket m is jourualed a roller formed with a head n of disk form which latter is cut with ratchet teeth as shown. Pivoted to the bracket m isa lever 0 one of whose ends extends substantially parallel Wlth sald bracket'and terminates immediately over the ratchetwdiskl n. The other mg g and terminates with a ball which forms a clapper for use with a hell psccuredto the outside of said case 9. Thearrangement of theratchet-disk, lever and bell is such that the rotation of said ratchet-disk will serve to ring the bell. It will he noticed that, norm ally the roller n (that bears the ratchetdisk) is not in contact with the flange h of When the complete coiler'is'in til the latter is filled. As the sliver continues to coil itself upon the filled can it engages the lower face of disk h and crowds said disk upward, as shown in dottedlines in Fig; 5,

'anoe thatnowresultfrom allowing the cans to become too tightly packed with sliver. 1 Havingdescribed my invention, I claim' 7 ported coiler-disk and mechanism for revolvthusforcing the flange h intojengagement with the roller n andcausing thelattertoroe tate. This simultaneously sets in revolution the attendant is called to the filled can. By regulating the weight of disk h the sliver may be coiled in the can with any desired degree of compactness. i I

My alarm attachment maybe cheaply appliedto coilers nowincommon use andwili l serve to avoid much of the Waste and annoy- In a coiler, in combination, a looselysun ing the same, a ratchet-disk-located in the Vertical path of said disk, and abell and clapper; said clapper being locatedin the pathof the ratchehdisk and actuated thereby, substantially as specified.
